Just a couple of more reasons AM's have a more difficult time a night in Florida: Most of our fulltime AM stations have to either reduce power and/or utilize a highly directional antenna array/pattern at night. Most shoot their signals out over the water. And most of the major Florida metros have outgrown the AM signals (especially at night), which were originally designed to serve their city of license and surrounding municipalities when the metros were much smaller. Regarding, why some of the talkers have moved around on the dial - Andy Johnson has had mostly lease or time broker agreements - and has been subject to ownership and format changes, etc. WBOB hasn't shifted around on the dial, until now, but suffered from too many programming/ownership/call-letter changes over the past 15 years or so. Actually, it's ironic that 1320 WBOB was just sold - their current line up of Bill Bennett, Laura Ingraham, Glenn Beck, Mark Levin and others, appears to have been the strongest national schedule they ever put together. All they needed was to institute some more local elements, local news and traffic, for example, and they would most likely continue to grow a loyal conservative audience. Slow and steady wins - WOKV has put together a very good, dependable product - but it's taken them over 20 years to do so, and to their credit, through some ownership and management changes. If you remember, in the early days, WOKV (which was then on 600) scrambled to improve their signal by leasing 100.7 for a time. And in the more recent years, despite now being a market leader, and having moved to the best 50,000 watt non-directional daytime AM signal at 690 in Jacksonville, and possibly Florida, Cox spent over 6 million to secure a place for their format on FM at 106.5 - and it's only a class A. Even though 690 has been upped to 25,000 watts at night, that 6 tower directional still misses a large part of the metro at night. It's my guess that if they ever had a serious News/Talk competitor, they would move 'OKV to one of their 100,000 watt facilities.
